Also Glenn, Colusa, Yuba and northern Sutter counties are covered by the alert.

Sustained north winds can be expected in the 10 to 20 mph range with gusts as high as 30 mph.

Daytime humidity could drop as low as 10 percent.

The mixture of these elements can result in “extreme fire behavior” where what should be small blazes can erupt into significant conflagrations.

A separate press announcement about the weather conditions said the forecasters anticipate a cooling period by tonight and “potentially periods of wet weather expected Tuesday through [the] rest of the week,” according to the forecasters.

Winds will shift and should be coming out of the south again with the possibility of gusts about 35 mph.
